JOHN W. HASBURG, OF CHICAGO, ILLINOIS.

MACHINE FOR SPREADING 0R FORMING PAINT.

Specification of Letters Patent.

Application filed December 4, 1911. Serial No. 663,778.

To all whom it may concern Be it known that I, JoI-IN WV. I'IASBURG, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Machines for Spreading or Forming Paint, of which the following is a specification.

My invention relates to improvements 1n paint spreading or forming machines.

In the manufacture of gold paintfor or namental decoration of ceramic and glass ware it is my usual custom to prepare such material, for shipment and use, on a glass palette made of a piece of ordinary window glass approximately three inches square, and then cover the paint by scaling to the surface of the plate a cup-shape closure having surrounding fiat edges to provide a substantially air tight seal to protect the paint against the deleterious influence of the atmosphere, and to protect it against contami nation by particles of dust. The paint is very valuable, and it must therefore be handled with care, and as it is used by artists its presentable appearance must be pleasing and attractive. The paint is deposited upon the glass palette and it is sufficiently mastic in character as to adhere thereto. It is spread out on the palette into a disk-like mass. It is commercially necessary that the paint mass, in the various packages, shall be uniform in size and thickness so as to avoid the appearance of unequal quantities therein.

My present invention has for its object to provide a machine whereby paint may be quickly and conveniently spread upon its palette in a uniform mass of artistic appearance, and whereby the working surface of the glass is presented always in a plane at ninety degrees from the axis of the rotating, paint spreading tool.

Qther and further objects of my invention will become readily apparent to persons skilled in the art from a consideration of the following description taken in conjunction with the drawings, wherein:

Figure 1 is an elevation of the spreading machine partly in section; Fig. 2 is an enlarged fragment of the machine showing parts of the upper portion in section; Fig. 3 is a further enlarged, broken away detail in section; Fig. 1 is an isometric view of the palette holder; Fig. 5 is a side view of the spreading blade in position of rest; Fig. 6 is a similar view of same in working position; Fig. 7 is a modification, showing a different form of blade that may be used; Fig. 8 is a perspective view of the blade; Fig. 9 is an enlarged section, taken on line 9-9 of Fig. 1.

In all of the views the same reference characters indicate similar parts.

In my co-pending application for forming paint and similar materials, Serial #6219 18, filed April lath, 1911, I have shown and described a frame and certain parts thereof similar in general character to the machine illustrated in this application.

My present invention has especial referlatent'ed Mar. 10, 191-1.

once to means for presenting the glass palette to the spreading tool, and to a pecuhar shape tool, and manual means for moving same in a vertical plane with reference to the palette.

On the base part 10 a frame 11 is super posed. A plate holder 12 is mounted for vertical movement on a tubular support, or shaft 13, conveniently by screw threaded engagement, as at 14. The plate holder 12 has overhanging ledges 15 on three of its sides, under which ledge the plate or palette is inserted from the open side. Three con tact screws 16 take through the respective ledges and are vertically adjustable therein. They afford stops against which the upper surface of the palette contacts at the time when it is presented to the spreading tool. The plate holder has a central recess 17 within which an open, helical cushion spring 18 normally rests in a holder 19. The spring holder is connected to a vertically movable stem 20, as by screw threaded engagement 21. Then the stem 20 is raised, as in Fig. 3, the upper surface of the cushion spring is brought into contact with the under surface of the palette 22, thereby to raise the palette until its upper surface is brought into contact with the three adjustable screws 16, so that by this means the paint-receiving surface of the palette is always presented to the spreading tool or blade in a plane at ninety degrees from the axis of said tool, thereby to insure uniformity of thickness of paint upon the palette. The cushion 18 is of sullicient strength to maintain the palette at all times in raised osition and instead of bein a S)1l11 shown, it can as well be made of any yieldmaterial, such as sponge rubber, or the 1 re. 1

A spreading tool comprising a thin blade 23 is preferably bent upon itself, as shown in Figs. 5 and 6, to give it its preferred resilience, having its upper edge secured to an arm 24 which in turn is secured to a collar 25. The collar is removably secured to a vertically movable, rotatable spindle 26, as by a set screw 27, or the like. The blade terminates at the vertical axis of the spindle 26. Now it is evident that, if the blade 23 be rotated above the palette 22, the blade will sweep over the presented surface of the palette in a precise parallel plane regardless of the variation in the thickness of the glass palettes or the lack of uniformity of thickness in any given palette, and thereby the formed paint deposit may be made uniform in thickness and size.

The forming blade and palette are moved into operative positions by the following means: In the base part 10 is a vertically movable tube 13 which carries on its upper end the palette holder 12 and provided with a feather 23 which moves freely in a spline .29 made into the base part 10 to prevent rotation of the tube. A collar affords a stop to limit the downward movement of the tube 13. To the lower end of the tube 13 there is connected a bearing casting 31, secured thereto by screw-threaded connection, as at 32, or otherwise. The casting 31 has a transversely disposed bore 33 which has a larger vertical dimension than horizontal dimension, to permit lost motion, vertical movement for the pin 34 therein. A foot treadle is pivoted to the base, as at 36,

and is held normally raised, as by a spring 37. An adjustable stop 38 provides a means for terminating the upper movement of the tube 13 to which the lever 35 is connected, as by a connecting rod 39. The pin 34 retains the connecting rod in association with the tube 34. The rod 20 directly carries the resilient palette supporting means 1819 at its upper end, its lower end rests upon the connecting rod bearing, as at 40. A recess 41 permits limited vertical movement of the connecting rod with reference to the bearing casting 31. From this arrangement it will be observed that, when a palette is inserted in the holder 12, as shown in Fig. 3, and the treadle 35 is depressed, the initial movement of the treadle raises the connecting rod 39 in the bearing 31 and thereby the rod 20 is raised to a limited extent but suthcient to bring the cushion spring 18 into contact with the lower surface of the palette and raise it until its top surface is brought into contact with the positioning screws 16, and further movement of the treadle 35, until it strikes the stop 38, raises the tube 13 and plate holder 12 to a predetermined height in position for application of the spreading tool 23 to the paint deposit then upon the palette.

Means for manipulating the spreading blade, 23, comprises a rotatable tube 42, vertically supported in bearings 11 11 of the frame 11. To the upper end thereof a driving pulley 43 is secured. Collars 44 prevent vertical movement of said tube. A centrally disposed, vertically movable spindle 26 passes through the tube 42 and is rotatably driven thereby by feather and spline connection 45. The upper end of the spindle 26 is circumferentially grooved, as at 46, for a loose fitting cap 47 that carries radially deposited pins, 48, for engagement in said groove. To the upper end of the cap 47 a lever 49 has pin and slot connection to provide for slight relative lateral motion therebetween, as when the spindle is raised and lowered by the lever. The lever has pivotal bearing support in the standard 50 and is yieldingly held normally in position shown in Fig. 1 by a spring 51. A connecting rod 52 connects the lever 49 with the hand lever 53, the latter being pivoted to the frame 11, as at 54. N ow when the handle 53 is depressed, by means of the connecting mechanism described, the tool 23 is likewise depressed. Normally the tool 23 has its trailing working edge substantially in position'shown in Fig. 5 but upon further pressure being applied to the handle 53 it may assume the position shown in Fig. 6, with its trailing working edge substantially in a radial line, or any intermediate position, depending upon the degree of pressure applied thereto.

The blade 23 sweeps over the upper surface of the palette and spreads the deposited paint thereon into a disk-like shape of uniform thickness and of diameter depending upon the quantity of paint and the pressure applied to the tool. The skill of the operator will determine the character of the fashioned deposit. If it is desirable to produce ornamental designs in the fashioned paintdeposit, the working edge of the tool 23 may be serrated, or notched, to produce the de sired configuration.

While I have herein described with some particularity a single embodiment of my invention, it is evident that changes may be made therein within the scope of the claims, without departing therefrom.
